About Alexandre

🎯 Are you looking for a robust dApp, a fluid and secure Web3 experience?
Whether you are launching an innovative blockchain project or need to strengthen a Web3 team, I am here to support you with efficiency, responsiveness and creativity.

👨‍💻 Who am I?
Fullstack developer, expert in React.js, Next.js, Tailwind CSS, and mastering the backend with Node.js and Express.js. I am also a specialist in Web3 integration (Ethers.js, Web3.js, Viem). My integrated approach allows me to connect everything: from the creation of smart contracts to the front-end interface that communicates with them, through the backend that manages all the business logic. My goal? To offer your users a complete, fluid and secure blockchain experience.

🚀 My method

1. Immersion: we exchange to understand your needs, your users and the blockchain specificities of your project.
2. Design & prototyping: I design modern, intuitive Web3 interfaces that are aligned with your decentralized identity.
3. Agile development: I build clean, secure code (smart contracts and backend), responsive and optimized for blockchain interaction, in constant connection with you.
4. Validation & iterations: we adjust the last details together for an impeccable and robust final rendering.

🤝 Why work together?
âś… Web3 product vision + reliable technical execution
âś… Clear & responsive communication
âś… Decentralized user experience at the heart of the process
âś… Custom, secure and scalable deliverables for the blockchain ecosystem

✨ A Web3/dApp/Blockchain project to launch? A blockchain product to evolve? A team to strengthen?
Let's talk about it and build together a decentralized solution that makes sense — and has impact.
